This study investigates the effect of keyword portfolio characteristics on sales in paid search advertising. The authors propose two keyword portfolio characteristics (variety and disparity) and examine the effects of portfolio variety and portfolio disparity on direct and indirect sales in both PC and mobile environment.

By conducting a field study at a large e-commerce platform, the authors use a negative binomial model to develop empirical findings that provide insights into paid search advertising strategies.

For main effect, (1) portfolio variety has a negative effect on direct sales. However, (2) portfolio disparity has positive effects on both direct and indirect sales. Advertising channels influence the contribution of keyword portfolio to sales. (3) On mobile devices, portfolio variety positively affects both direct and indirect sales. However, portfolio disparity negatively affects both direct and indirect sales. (4) On PCs, portfolio variety negatively affects both direct and indirect sales. However, portfolio disparity positively affects both direct and indirect sales on PC.

The findings provide advertisers with insights into how to manage keyword portfolio between mobile devices and PCs.

The current study shifts the attention from keyword to keywords (keyword portfolio), which extends the paid search literature. Moreover, it also contributes to the literature by comparing the relative effectiveness of mobile and PC search advertising.

This research reviews numerous studies of the relationship between consumer knowledge and external search in conventional marketing channels to investigate differences among these studies that have produced conflicting results. The findings provide a benchmark for future researchers and practitioners seeking to gain insight into consumer information search processes unfolding in the new environment of online, mobile, and social networking channels.

A meta-analysis of an extensive array of empirical studies of the relationship between consumer knowledge and external information search was conducted. Regression analysis was used to test whether certain characteristics in the studies can explain variability in the effect sizes in which effect sizes are entered as dependent variables and moderators as independent variables.

Objective and subjective knowledge tend to increase search, while direct experience tends to reduce search. Consumers with higher objective knowledge search more when pursuing credence products. However, they search relatively less when pursuing search products. Consumers with higher subjective knowledge are much more likely to search in the context of experience products, but as is the case for objective knowledge having little effect on search for experience products, subjective knowledge has no significant effect on information seeking for search products. In addition, objective knowledge facilitates more information search in a complex decision-making context while higher subjective knowledge fosters more external information search in a simple decision-marketing context. Finally, the findings indicate that the knowledge search relationship reflects strong linkage in the pre-Internet era.

Relatively little is known about how the relationship between knowledge and information search varies across different types of products in simple or complex decision-making contexts. This study begins to fill this gap by providing insight into the relative importance of objective knowledge, subjective knowledge, and direct experience in influencing consumer information search activities for search, experience, and credence products in simple or complex decision-making contexts.

This paper uses a mix of qualitative and quantitative methodology to analyse differences between Finnish and American web searchers (n=27 per country) in their choice of initial search strategies (direct address, subject directory and search engines) and their reasoning underlying these choices, with data gathered via a questionnaire. The paper looks at these differences for four types of questions with two variables: closed/open and predictable/unpredictable source of answer (n=16 questions per searcher; total n=864 questions). The paper found significant differences between the two groups’ initial search strategies and for three of the four types of questions. The reasoning varied across countries and questions as well, with Finns mentioning fewer reasons although both groups mentioned in aggregate a total of 1,284 reasons in twenty‐four reason categories. The reasoning indicated that both country groups considered not only question‐related reasons but also source‐ and search‐strategy related reasons in making their decision. The research raises questions about considering cultural differences in designing web search access mechanisms.

The application of “Google” econometrics (Geco) has evolved rapidly in recent years and can be applied in various fields of research. Based on accepted theories in existing economic literature, this paper seeks to contribute to the innovative use of research on Google search query data to provide a new innovative to property research.

In this study, existing data from Google Insights for Search (GI4S) is extended into a new potential source of consumer sentiment data based on visits to a commonly‐used UK online real‐estate agent platform (Rightmove.co.uk). In order to contribute to knowledge about the use of Geco's black box, namely the unknown sampling population and the specific search queries influencing the variables, the GI4S series are compared to direct web navigation.

The main finding from this study is that GI4S data produce immediate real‐time results with a high level of reliability in explaining the future volume of transactions and house prices in comparison to the direct website data. Furthermore, the results reveal that the number of visits to Rightmove.co.uk is driven by GI4S data and vice versa, and indeed without a contemporaneous relationship.

This study contributes to the new emerging and innovative field of research involving search engine data. It also contributes to the knowledge base about the increasing use of online consumer data in economic research in property markets.

The purpose of this paper is to evaluate of the results of a survey which asked people where they went online for their health information, why and what success they had. The prime purpose of the questionnaire was to obtain information on the audience for health information web sites and to obtain feedback as to what they used online health sites for. The focus was on two major publicly funded health internet sites: NHS Direct Online and the BBC web site.

An online survey was carried out with a population of internet users in the UK in the winter of 2004, yielding a sample of nearly 1,000 (923) people and a response rate of 4.4 per cent was achieved.

The survey identified that indeed both sites were well used although their users were very different in terms of how they arrived at each site and in terms of what they were looking for. Outcomes resulting from using the sites are discussed and compared. Though outcomes differed between NHS Direct Online and the BBC the data suggest that the national sites were not meeting the demanding information needs of some users.

It is the first time that two publicly funded national sites that aim to provide the UK population with health information are compared.

The purpose of this paper is to investigate whether or not mavens’ dissemination activities are likely to promote or hinder retailers’ store brand premiumisation attempts, by revealing the relationship between mavens’ price and non-price on-pack extrinsic cue search and their store brand purchasing behaviours.

The paper adopts a hypothetic-deductive approach and develops a model of mavens’ store brand purchasing behaviour. The model is tested using SEM on a US data set containing 457 respondents. A full discussion of the direct, indirect and total effects is provided.

Mavens’ store brand purchasing behaviours are strongly linked to their price search activities and negatively related to their use of non-price on-pack extrinsic cues. This indicates that their dissemination activities are likely to stress lower prices and hence price competition rather than promote other cues used to infer quality. Thus, mavens are likely to inhibit retailers’ store brand premiumisation attempts. Mavens’ investments in time engaged in search activities are strongly linked to social returns rather than private financial savings.

The work is based on data collected using an online survey in one region of the USA where store brands are not as prevalent in other countries such as the UK.

The investigation of non-price on-pack extrinsic cues reduces mavens’ store brand purchasing behaviours while the use of price cues increases them. This suggests that even with mavens’ market expertise that a non-price extrinsic cue deficit continues to exist for these products. Consequently, retailers need to re-examine and rework the cues contained on pack to convey more positive consumption-related information if mavens are to become store brand advocates.

Rather than conceptualising the maven as possessing market wide knowledge, this research adopts a domain specific perspective arguing that price mavenism can be distinguished from product-related mavenism with consequences for the set of extrinsic cues used as part of the maven’s search process. In doing so, it reveals the conflicting effects that these maven dimensions have on purchasing behaviours and the likely effects on mavens’ dissemination activities.

The n‐dimensional direct search algorithm, DIRECT, developed by Jones, Perttunen, and Stuckman has attracted recent attention from the multidisciplinary design optimization community. Since DIRECT only requires function values (or ranking) and balances global exploration with local refinement better than n‐dimensional bisection, it is well suited to the noisy function values typical of realistic simulations. While not efficient for high accuracy optimization, DIRECT is appropriate for the sort of global design space exploration done in large scale engineering design. Direct and pattern search schemes have the potential to exploit massive parallelism, but efficient use of massively parallel machines is non‐trivial to achieve. A fully‐distributed control version of DIRECT that is designed for massively parallel (distributed memory) architectures is presented. Parallel results are presented for a multidisciplinary design optimization problem – configuration design of a high speed civil transport.

The purpose of this paper is to present the findings of an empirical study of information behaviour of young Slovenian researchers.

Built on some well‐known models of scholarly information behaviour the study complements a previously conducted study of the same population, which focused on the aspects of user friendliness. This second study is an attempt to shape a more detailed picture of the investigated user group. Presented are types of scholarly information behaviour, enriched by some complementary issues regarding their behaviour as digital users.

The respondents were found to express many of the features of both digital scholars and other users of digital technology. Direct searching and power browsing are most often expressed searching behaviours; also common are probing and accessing. Collecting behaviour is mostly expressed through “squirrelling”, and sometimes gathering. Satisfaction with the system and with search results is very influential, but sometimes not decisive, for the user to stay with the system, since attention to the content of the results is also very strong.

The rationale for the study was that understanding users' information behaviour is crucial in the design of their information tools.

Scholarly information behaviour has been extensively studied in Western countries, however, studies of this nature are not so common in Slovenian scholarly literature. As such, this study is one of the first to tackle this issue.

Few issues in recent times have so provoked debate and dissention within the library field as has the concept of fees for user services. The issue has aroused the passions of our profession precisely because its roots and implications extend far beyond the confines of just one service discipline. Its reflection is mirrored in national debates about the proper spheres of the public and private sectors—in matters of information generation and distribution, certainly, but in a host of other social ramifications as well, amounting virtually to a debate about the most basic values which we have long assumed to constitute the very framework of our democratic and humanistic society.
